IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 205.509, dated July 2,1878; application filed February 28, 1578.

To all whom it may concern:

Be it known that I, CHARLES P. Snow, of Freeport, in the county ofStephenson and State of Illinois, have invented a new and usefulImprovement in Plows, of which the following is a specification,reference being had to the accompanying drawings.

The invention relates to an improvement in plows; and consists in thedevices hereinafter set forth.

The object of the invention is to provide a means for holding the plowin a rigid position, or for elevating or depressing it, and also forallowing it to be moved either to the right or left without elevatingthe plow-beam.

The invention also provides a means for lowering or raising the body ofthe franie carrying the plow.

In the accompanying drawings, Figure 1 is a side elevation of theinvention. Fig. 2 is a top view of same with the drivers seat removed.Fig.3 is a detached plan view of the gearing operating the plow-beam.

A represents the frame of the device, which is provided on its rear endwith the shaft B and upon each side with the vertical sleeves orbearings D, in which are properly placed the bars a, having teeth b uponone of their edges,

which teeth are designed to engage a suitable pawl or other device. (notshown,) and thereby adjust the position of the bars a in the sleeves.

The lower ends of the bars a are pivotally secured upon the axles d injuxtaposition to the supportingwheels 0, also mounted upon the axles d.It is obvious, according as the bars a are either elevated or depressed,that the axles (1 will be brought nearer the ground or be fartherremoved therefrom, and that the frame A will consequently be similarlyaffected.

About the longitudinal center of the implement the bars f pass from thefront edge of the frame A, and have their rear ends secured to the shaftB, centrally above which is supplied an operators seat, g.

Upon the shaft B, between the rear ends of the bars f, is mounted thesleeve h, furnished with the rearwardly-projecting lips or flanges t,between which is loosely secured the front end of the plow-beam I by asuitable bolt and nut, the said front end of the plow-beam beingpreferably somewhat wider than its rear end, though it may be of anydesired dimensions. The rear end of the plow-beam I, after extendingrearward a proper distance, turns downward, and is supplied with asuitable plowshare, as shown.

At the ends of the shaft B are secured the ends of the curved bar at,which bulges rearward, and is provided upon its under surface, about itscenter, with the downwardly-projecting lips 02, the distance betweenwhich should be about equal to the width of the plow-beam l, so that, when desired, the bar at may be lowered upon the said plow-beam and thelips it passed down upon each side thereof, thus securing the plow-beamin a fixed position.

To the rear portion of the bar at is affixed the rear end of the lever19, the front end Whereof extends forward to within suitable reach ofthe operators foot, thereby affording a convenient means for raising thebar at from the plow-beam or lowering it upon the same, and for allowingthe plow-beam to be swung either to the right or left, or be secured ina rigid position between the lips a.

Upon one edge of the sleeve h is furnished the segmental gearing t,which extends forward and meshes with the similar section of segmentalgearing u, pivoted on the axle w and supplied with the lever 00, whichextends forward, and is furnished with a suitable stud on its face toengage properly-placed apertures constructed in the rack E secured tothe bar f.

The purpose of the segmental gearing, lever, and rack is to provide ameans for elevating or depressing the point of the plowshare. Thus, whenthe plow is digging too deep, the operator need simply raise the frontend of the lever a: and insert its stud in one of the apertures in therack E, thereby causing the elevation of the plowshare and looking it insuch position.

To depress the plowshare, it is simply necessary to reverse theabove-mentioned movement of the lever It is evident that when the bar atis elevated the plow beam and share are perfectly free to turn upontheir pivot either to the right or left, and that when the bar m islowered the lips n will hold the plow-beam in a fixed position.

Vhat I claim as my invention, and desire to secure by Letters Patent.is-

1. The segmental gearing t a, lever 00, and rack E, in combination Withthe sleeve 71 lips 1". plow-beam l, and bar m, substantially as setforth.

2. As a means for allowing; the lateral movement of the plow-beam l, thecurved bar 722, hinged at each end on the axle B, and provided on itsunder surface With the lips 11, and on its upper surface With thefoot-lever p, in combination with the sleeve 71 having lips i, betweenwhich the plow-beam is pivoted, substantially as set forth.

In testimony that I claim the foregoing improvement in plows, as abovedescribed, I have hereunto set my hand this 12th day of February 1878.
